中文摘要:针对一种重要对抗措施——核弹头的反模拟气球诱饵,提出了一些有益于突防的具体措施。通过热网络数学模型及差分法,分别对不同大小空间球形目标的白天和夜间表面温度场分布进行了计算。结果表明,为了使诱饵在白天和夜间都能使用,在设计时采用一组不同大小的诱饵,使其表面温度分布在含弹头气球表面温度的附近两侧。这样既可破坏美国导弹防御系统(National Missile Defense, NMD)基于大小识别目标的能力,又可增加对方识别目标的复杂性。

Influence of the Size of Space Spherical Target on Thermal Effect
Abstract:Aiming at “Anti-Simulation Balloon Decoys for Nuclear Warheads”,which is one of the important countermeasures, some specific measures beneficial to penetration are proposed. By means of the thermal network model and difference method, the surface temperature distributions of spherical objects with different sizes in daytime and nighttime are calculated. The results show that in order to make the decoys usable both during the day and at night, a group of different sizes of decoys is designed so that the surface temperature of the decoys is distributed on both sides of the surface temperature of the balloon containing the warhead. This measure can undermine U.S. National Missile Defense (NMD) system′s ability to identify targets based on size and increase the complexity of identifying targets as well.
